JOHN E. MANNEN AND WILLIS M. ESTERLY, OF CLEVELAND, OHIO.

LAUNDRY CLOTH ES-DRIER.

SPECIFICATION forming part of Letters Patent No. 791,565, dated June 6, 1905 I Application filed December 16, 1904.v Serial No. 237,153.

To all whom, it may concern:

Be it known that we, JOHN E. MANNEN and WILLIS M. ESTERLY, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio," have invented certain new and useful Improvements in Laundry Clothes-Driers; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to improvements in laundry clothes-driers; and the invention consists in the construction and combination of parts substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspectiveelevation of the complete instalment, including the drier and stove or range in connection therewith. Fig. 2 is a cross-section horizontally through the stove and the drier over the hot air or heating chamber on line 3 y, Fig. 3, and showing the air and draft passages and other portions in section; and Fig. 3 is a vertical sectional elevation of the said parts corresponding to line on m, Fig. 2. I

The invention as thus disclosed is an improvement on our Letters Patent of the United States issued June 23, 1903, No. 731,481, in

v tion of the main parts shown herein; but the details of the present construction materially difler from those disclosed in said patent, as will be more clearly seen in the further description. These details appertain to the hot air and draft passages between the heater and the drier, whereby the same volume of heat is made much more effective than formerly.

A represents the stove, range, or heater, and B the drier-chamber, which may be of any desired size, according to the work to be done and the room wherein it may be erected.

B represents the clothes racks or supports, which, however, do not enter into this case as new features.

C is a heater chamber having the dimen- Sions approximately of the drier in plan and 0 and at its outlet 0 outline and of a depth eight to twelve inches and supported within the drier-walls, but in this instance on legs or supports 0, so as to be in position to communicate with the fluepas'sages of the stove or range A at its inlet If the direct damper a from the stovebe closed, the products of combustion will travel therefrom through passage c into the heater-chamber C and thence around the triangular fresh-air-inlet center 0 to outlet 0 and out through escape-pipe F to the chimney. The size of the air-heating chamberC is such and thetravel of the products of combustion is so indirect therein that only a very small percentage of the heat reaches the point of escape 'to the outer air, and by carrying the heat around the fresh-airinlet passage defined by the substantially triangular inner wall C of said chamber G the heat is not only caused to make a relatively large circuit, but is thrown well out toward the outer walls of the drier, thus materially promoting diffusion of heat and doing the most effective work possible within the area reached. 7

i The fresh air enters the chamber or oven (0 of the stove through opening a by fresh-air pipe a from without, and the air travels thence into the large area (J beneath chamber C, and while the bulk of the air rises from here through the triangular opening G a portion of it also rises about the outer walls of said chamber and between the same and speedy impartation possible of the heat from' said chamber through its walls and top to the drier and to the end that none of the heat practically, be lost. Clean-out openings Gr may be used here and there.

The triangular opening through the middle of the heating-chamber C has walls 0, connecting its flaring sides 0 with the front of said chamber and serving to divide the passages c and c from each other, and the inflowing hot air or products of combustion strike the inclined or deflecting wall 0 and are caused to flow outward, so as to get into the circulation around angle a, which further promotes diffusion and radiation of the heat.

No dampers are needed in the drum C, and it is easily cleaned through holes G in its sides, and its walls are just far enough from the outer wall B to aflord an upward airdraft between them, proportioned relatively as seen in Fig. 2.

What we claim is 1. In laundry elothes-driers, a drier-chamber and a heating-chamber therein provided with a walled air-passage vertically through its center, in combination with an outside stove having inlet and outlet passages for the products of combustion, and the wall of the drier having openings communicating with said passages, substantially as described.

2. In laundry clothes-driers, a drier-chamber, a heating-chamber in the bottom thereof having a substantially triangular opening vertically through its center with a stove, and inlet and outlet'passages between said heating-chamber and stove with a division-wall between them, substantially as described.

3. In laundry clothes-driers, adrying-chamher, a heating-chamber in the bottom thereof having inlets and outlets and a substantially triangular opening through the center thereof having walls inclining outwardly and rearwardly from said openings, and a stove having draft-passages in open relation to the said inlets and outlets of the heating-chamber, substantially as described.

In testimony whereof we sign this specification in the presence of two witnesses.
